How to use the Marketplace Image Optimizer

Resize, crop, clean the background and compress product images to each marketplace's exact specification — in batch, in your browser.

It's part of the MagicBG toolbox— a suite of free, browser-based utilities that never upload your files anywhere.

• Listings accepted the first time, with zoom enabled
• A consistent catalog look across every channel
• Faster page loads thanks to compressed, metadata-free files

1. 1

   Upload one or many product photos (JPG, PNG or WebP).

2. 2

   Pick your marketplace — Amazon, Shopify, Etsy, eBay, Walmart or Facebook Marketplace.

3. 3

   Choose a background, then optimize and download the files individually or as a ZIP.

• Six marketplace presets with the correct size, ratio, format and quality
• Optional AI background removal, white or custom colour backgrounds
• Batch processing with live progress and ZIP export
• Low-resolution warnings instead of blurry upscaling

• Amazon and Walmart main images
• Shopify catalog uploads
• Etsy, eBay and Facebook Marketplace listings

• Shoot at 2000 px or more so every preset has enough resolution.
• Use white backgrounds for main images and lifestyle shots for secondary photos.
• Export JPG for listings and PNG only when transparency is required.
